In terms of satellite R&D, in accordance with the judgment of satellite technology development trend and commercial development mode, the core technical team has broken through the traditional design concept and adopted the technical route of "satellite platform and load integration". After four times of progress in ten years, the weight of the satellite has been reduced to 20kg from 400kg of the initial generation, and the R&D cost has also been reduced to 1/20 of the original. 

At present, CGSTL has an annual output of more than 200 satellites, and has achieved self-developed mass production of core single machines, including magnetic torquer, magnetometer, central computer, star sensor and imaging processing box, etc., and gradually formed a whole industrial chain cluster with satellite R&D and production as the core.

2. Communication satellite 

With the mature technical foundation in satellite R&D, since 2019, CGSTL has undertaken and successfully completed a number of national communication satellite R&D tasks. At present, CGSTL has become an important supplier of communication satellites in China. Now, CGSTL is actively planning to build a communication satellite production line. So far, it has initially developed an annual R&D capability of 200 communication satellites. 

In addition, CGSTL has completed the R&D of satellite-to-ground laser terminal, inter-satellite laser terminal and ground laser station, completed the whole process test of satellite-to-ground and inter-satellite 100Gbps laser data transmission, and established a space high-speed laser data transmission network test system.

3. Satellite constellation management 

CGSTL has built an automatic digital satellite constellation operation control system, realizing automatic satellite operation, requirement, data production interface and distribution, and has the comprehensive ability of telecontrol telemetry and satellite operation. Image data of newly 10 million square kilometers can be obtained every day, and daily imaging tasks of 1,700 times can be completed. The dispatching time less than 1 minute, the daily digital transmission tasks can be 300 circles. In a day, any place in the world can be visited for 37-39 times a day, and CGSTL has the ability to cover the whole world 6 times in a year and cover whole China every half month.
